Myopic Astigmatism?

I have a perscription for my eyesight, leff: sph -0.75 cyl -2.25, right: sph -0.50 cyl -2.25. Thing i wanna ask is, i am 26 when you think the development of myopic Astigmatism will stop, my previous glasses 2 years ago were both eyes sph -1.00 cyl -1.50 and second question, what do you advise me to wear glasses or contact lenses, whichone would give me the best possible eyesight. Thanks in advance
Actually, the prescriptions from this year and last year are not very different. The explanation as to why that is gets into optics and stuff that I won't go into, but what we call the 'equivalent sphere' is nearly the same in both. Even though the numbers have changed, it doesn't necessarily mean your eyes are getting worse. When people have high astigmatism (the front surface of the eye is not perfectly round-- this is corrected by the cyl in the prescription) it can be more difficult to adapt glasses when the full correction is given right away. It could be that the Doctor changed the numbers last time to give you the same effective power and a greater chance to get used to the cylindrical prescription. Now (s)he is increasing it in smaller steps closer to where it should be, and the other numbers must be changed to keep the same effective power. Basically, when writing a prescription, the doctor takes more into account than just the numbers on the machine. :-)

Because astigmatism has a direction (the axis on the prescription) you would get the best Vision with glasses because they stay in the same position all the time. When a person wears contact lenses, the lens moves a bit each time you blink, and most people with astigmatism find that vision fluctuates a little with each blink until the lens stablizes again to the proper position. Also, the higher your amount of astigmatism (and yours is moderately high), the more sensitive you will be to blur when the lens has rotated. While there are Contact lenses to correct astigmatism, we are limited by the parameters that the company makes, which also means there may be a compromise to the best vision you can get with them. So for the 'best possible eyesight', as you put it, I think glasses are the way to go.
